Hours expired damper

Hours expired damper

Whilst speaking with an operator recently, the question came up about whether it was possible to save time and money by not replacing the damper. We gave them the full technical explanation and it made me think that it was worth putting together the correct protocol when it comes to the dampers in your critical diesel engine, to help you make the right decisions. There are two types of dampers: viscous and rubber bonded. Viscous dampers come in...

Caterpillar 3126A timing issues

Caterpillar 3126A timing issues

Our engineers have been working on an interesting engine in the workshop recently which I thought I’d share with you. The engine in question was sent to us by a marine operator for a full overhaul: nothing out of the ordinary there. The engine in question, however, IS out of the ordinary: A Cat 3126A with 2 valve cylinder heads and combined pump injectors. Caterpillar only made a few of these engines, and thanks to various issues with timing,...

Cylinder Identification

Cylinder Identification

During a recent job, we realised that the cylinders on the engine had been misidentified. It reminded me of a much more serious problem we’ve seen before, which you can see in the picture below. All this was as a result of the A-bank pistons being fitted in the B-bank and vice versa. Not only is it critical to return the pistons to the correct bank of the engine, but when it comes to communicating, resolving and recording engine information, it...

Magnetic Pickup Probe Issue

Magnetic Pickup Probe Issue

Our engineers were on-site recently, carrying out a top-end overhaul on an emergency generator engine when they came across an issue that is often overlooked. But if left unchecked, it can drastically impair your engine’s performance. As part of the works, our team inspected the magnetic speed pickup… You can see from the picture below that the flywheel magnetic pick-up was covered in a 1mm depth of black dirt. The dirt on the probe was...

Excessive Engine Backlash

Excessive Engine Backlash

We’ve just started supporting a new marine operator, and the other day they were getting some concerning noises following the overhaul of their Caterpillar 3406 engine by another firm. As it turned out, a fundamental setting had been missed. Once on the vessel, we checked the backlash of the timing gears and found them to be out of tolerance, and the result was this damage to the teeth on the gears: The engine arrived in our workshop, where we...

Seized turbocharger back on-line

Seized turbocharger back on-line

If you are reliant on “heritage” engine models, or those simply not made anymore, then chances are you will have experienced supply problems for ongoing maintenance or repairs. Sourcing of spares can usually be overcome with a bit of digging, but when it comes to major assemblies, it can be a lot more complicated, not to mention expensive! One of our clients found themselves in that position recently with two Sulzer LAG46 Turbochargers that had...
